periodic table, in chemistry, the organized array of all the chemical elements in order of increasing atomic number—i.e., the total number of protons in the atomic nucleus. When the chemical elements are thus arranged, there is a recurring pattern called the “periodic law” in their propert...

The periodic table of the elements contains all of thechemical elementsthat have been discovered or made; they are arranged, in the order of their atomic numbers, in seven horizontal periods, with the lanthanoids (lanthanum, 57, tolutetium, 71) and the actinoids (actinium, 89, tolawrenci...

Periodic Table of Elements - The periodic table is the tabular arrangement of all the chemical elements on the basis of their respective atomic numbers. In the periodic table, the vertical columns are called groups and the horizontal rows are called peri
High atomic weight elements mean higher density. A compact crystal structure will aid in driving the density up as a tighter packing pattern means more atoms per unit cell. Hence minerals containing lead, barium, or any elements in the 5th row of the periodic table will show much higher ...
Why is the periodic table shaped like it is? Organization of chemical elements in alphabetical order by their names (or symbols) doesn't tell us anything about their properties but it is useful when searching for an element. We can list elements in order of increasing atomic number but it ...
